Novel 2,3,4,9-tetrahydro- and 4,9-dihydro-1H-benzo[f]isoindole derivatives were synthesized from Juglone and amino-acid azomethines in 74–85% yields via 1,3-dipolar cycloaddition. The stereo- and regioselectivity of cycloaddition was confirmed by N

Recently, in a large scale screening test, we have found that S-((1,4-dimethoxy-9,10-dioxo-9,10-dihydroanthracen-2-yl)methyl)4-aminobenzenesulfonothioate, a chemically synthesized thiosulfonate derivative of quinone, possessed an antiplatelet activit
